mat to cell but separate cells
Hi all A problem I'm having is working out how to convert a mat array (say 1x5) to a cell array (1x5 -> NOT 1x1 containing a 1x5). In a loop it is just: xy=[4 5 6 7 8 9].'; z=cell(6,1) for i=1:6; z{i}=xy(i); end z is what I want at the end of it, and the above code will do the job, but, I don't want to use ... 15 Mar 2010 12:19

system of pde
Greetings, I am a new user of matlab and I have to solve a system of two Partial differential equations (PDE) of second order and three dimensions (time independent) with boundary conditions. The two unknowns are F(x,y,z) and P(x,y,z) and the equations (where N(....) refers to the nabla operator on the horizontal... 15 Mar 2010 08:58

ODE45 problem
Hey everyone. I am currently solving a set of ODE's for a biological system with an oscillatory behavior. The first model runs perfectly with the ode45 command, however the second one which is slightly different gives the following error: [t, y] = ode45(@dact, [0 20], [0 0]) Warning: Failure at t=4.828591e-03.... 15 Mar 2010 16:58

How to auto tune my PID?
I've developed a simulink-model for the revolution control of a PMSM (from Simpower library). But the auto-tune functionality of the PID is generating some errors ("To many outputs requested. Most likely cause is missing [] around left hand side that has a comma separated list expansion"). I've already watch the webin... 15 Mar 2010 18:08
